Diwali fatigue: Why late nights and festive routines leave you exhausted

Diwali celebrations often involve late nights, social gatherings, shopping and indulgent meals. However, changes in daily routines can leave people feeling unusually tired, even without strenuous physical activity. Irregular sleep, dehydration, heavy meals and festive stress can affect energy levels, concentration and mood.Dr. Poonam Vira Makhija, Full-time Consultant – General Medicine at Holy Family Hospital, Mumbai, explains why these habits can contribute to festive fatigue and how people can recover.Late nights, irregular meal timings, inadequate fluid intake, dehydration and overindulgence can take a toll on the body. These habits can leave people feeling tired, less attentive and easily distracted, even when they have not engaged in strenuous physical activity.HOW LATE NIGHTS DISRUPT YOUR BODY CLOCKThe body follows a 24-hour sleep-wake cycle known as the circadian rhythm, which regulates signals that determine when we feel sleepy and when we wake up. Staying up late, waking early and changes in sunlight exposure can disrupt this rhythm, affecting sleep and daytime alertness. Repeatedly getting insufficient sleep can lead to a build-up of sleep debt, causing headaches, mood changes, difficulty concentrating and slower reaction times.Dr. Makhija recommends that adults aim for seven to nine hours of sleep each night to support optimal health.HOW HEAVY MEALS AND EXCESS SUGAR AFFECT ENERGY Festive meals often include rich foods, sweets and larger portions than usual. Heavy or fatty foods may cause digestive discomfort, while foods high in sugar can lead to fluctuations in blood glucose levels. Eating large meals late at night can also trigger heartburn and disrupt sleep.Maintaining regular meal timings and eating appropriate portions can help prevent digestive discomfort and support steady energy levels.Caffeine may provide a temporary boost in alertness, but it cannot replace the restorative benefits of sleep. Consuming it in the evening can interfere with rest and increase sleepiness the following day, potentially creating a cycle of greater caffeine consumption.Although alcohol may initially make a person feel sleepy, it can disrupt sleep later in the night and cause repeated awakenings. It may also contribute to headaches, dizziness and reduced concentration the following day.CAN FESTIVE STRESS LEAVE YOU EXHAUSTED?Shopping, travelling, hosting guests and attending social events can create physical and mental strain. Stress can also interfere with the ability to relax and sleep properly.Dr. Makhija recommends setting realistic goals and pausing tasks when stress builds up. Avoiding an overly packed schedule can help make celebrations more manageable.Fatigue caused by disrupted routines may improve with adequate rest, hydration and a return to regular activities. However, persistent or worsening exhaustion that interferes with daily life should not be ignored.Underlying conditions such as anaemia, thyroid disease or an infection may also cause fatigue. If tiredness does not improve with rest, consult a doctor to identify the cause.WARNING SIGNS YOU SHOULD NOT IGNOREPersistent exhaustion, dizziness, palpitations and breathlessness should not automatically be attributed to late nights or festive activities. Recurring or unexplained symptoms warrant medical evaluation.Chest pain, difficulty breathing, fainting or palpitations accompanied by feeling unwell require immediate medical attention.HOW TO RESTORE YOUR SLEEP SCHEDULE AFTER DIWALIReturning to a consistent bedtime and wake-up time can help restore the body's usual rhythm after several nights of late celebrations. Adults should aim for seven to nine hours of sleep, allowing additional rest if needed.Gradually adjusting sleep timings, limiting screen use before bed and cutting back on caffeine can help re-establish a regular schedule.Adequate water intake and nutritious meals support normal bodily functions and energy levels. Morning daylight exposure can help regulate the body's internal clock, while walking and other physical activities may improve mood and sleep.HOW TO ENJOY DIWALI WITHOUT COMPROMISING YOUR HEALTHDr. Makhija recommends a few practical habits to help people enjoy the festivities while maintaining their well-being:Prioritise sleep: Avoid repeatedly sacrificing rest for late-night celebrations.Eat balanced meals: Keep portions reasonable and avoid heavy meals close to bedtime.Stay hydrated: Drink enough water throughout the day.Limit caffeine and alcohol: Be mindful of their effects on sleep and next-day alertness.Schedule breaks: Allow time to rest between shopping, travel and social commitments.Maintaining a balanced routine can help people enjoy Diwali while reducing the likelihood of fatigue disrupting their celebrations.- Ends
